TDA4471 - Multistandard Video-IF and Quasi Parallel Sound Processing

Description

The TDA4471 is an integrated bipolar circuit for full multistandard video/sound IF (VIF/SIF) signal processing in TV/VCR and Multimedia applications.

The circuit processes all TV video IF signals with negative modulation (e.g.

B/G standard), positive modulation (e.g.

Features

www.DataSheet4U.com TELEFUNKEN Semiconductors TDA4471 Multistandard Video-IF and Quasi Parallel Sound Processing Description The TDA4471 is an integrated bipolar circuit for full multistandard video/sound IF (VIF/SIF) signal processing in TV/VCR and Multimedia applications. The circuit processes all TV video IF signals with negative modulation (e.g. B/G standard), positive modulation (e.g. L standard) and the AM, FM/NICAM sound IF signals. Specially two video IF inputs (2 x VIF) in combination with one sound IF input (1 x SIF) and the common pinning with the TDA4474 gives flexibility to design a universal IF module for various applications.
